Patent JP-H04328861-A (JP)
Title: Semiconductor integrated circuit device and manufacture thereof
Inventor: YOSHIDA HIROYUKI
IPC: H01L21/822
Filed: 1991-04-26
Abstract: PURPOSE:To make it possible to perform reliably an inter-element isolation by a method wherein a high-concentration and inverse conductivity type semiconductor layer is formed up to the position of a depth, which includes at least first and second impurity diffused regions, of a groove and an insulating film is provided on the lower part of the groove. CONSTITUTION:In a memory cell, an insulating film 54 is formed on the region other than the region on the whole periphery of the upper part of the wall surface of a trench-shaped groove 20 formed in one main surface of a P<--> semiconductor substrate 81. An N<+> impurity diffused region 53 is annularly formed in the one main surface on the periphery of the upper part of the groove 20 and an N<+> source region 22 is continuously connected to this region 53 and is formed in the one main surface. A high-concentration P-type semiconductor layer 80 is formed up to the position of the intermediate depth of the groove 20 in a state that it completely includes these regions 53 and 22. The concentration of this layer 80 is a concentration higher than that of the lower region of the groove 20 and the conductivity type of the layer 80 is an inverse conductivity type to those of the N<+> diffused regions 53 and 22. Thereby, an inter-element isolation is reliably performed and an alpha-ray resistance can be made sufficient.

Title: Power-supply voltage detecting circuit
Inventor: HORII SHIGERU
IPC: G01R19/155
Filed: 1981-08-10
Abstract: PURPOSE:To increase the current consumption of a voltage detecting circuit only during detecting operation while suppressing it during other operation, by connecting a CMOS logical element in series to the voltage detector which has less output voltage variation than power-supply voltage variation. CONSTITUTION:In a voltage detector 4 applied with a power-supply voltage VB, a resistance R is so set that a voltage VD drops more slowly that the power- supply voltage VB, so the power consumption of this voltage detector 4 is small. On the other hand, the threshold level Vth of a CMOS inverter L1 applied with the power-supply voltage VB is nearly by half of power-supply voltage. If the power-supply voltage VB drops and the voltages VD and Vth come cross at a to time, the inverter L1 operate and the output level varies from a state H to a state L to increase the current consumption (i) of the detecting circuit 4 in a pulse shape. Consequently the drop of the terminal voltage is speeded when the battery is nearly consumed to improve the terminal voltage characteristics in the life termination period of the battery.

Abstract: PURPOSE: To bond the part leads tightly and perfectly in a simple constitution, by forcing to cool the heating tip end or soldering part, when reflow-soldering by always pressing the heating tip to the part leads.  
     CONSTITUTION: The temperature at the end of a heating tip 3 of reflow soldering device of continuous heating system is controlled by the thermocouple welded  thereto and a control device. The heating tip 3 is positioned to the leads of multi- terminal lead part of Lsi or the like, and the microswitch is operated when reaching  the set pressurizing force of the pressurizing device to apply pressurization and heating to the lead part for the set time of the timer, thus performing reflow soldering.  Simultaneously with the end time of this, a timer for cooling is operated, and air is  forced out from the end 5 of a cooling pipe 9 by means of a solenoid valve 7.

IPC: G21K5/00
Filed: 1990-05-18
Abstract: PURPOSE:To quickly photograph bodies to be examined different in neutron transmittivity to improve the operating ratio by providing a replacing means to replace guide tube units. CONSTITUTION:Cold neutrons enter into a collimator vacuum vessel 22 from a speed selector 18. At this time, guide tube units 28a of a conduit 28 is the lowest layer are arranged in the advancing path of neutrons. Cold neutrons successively pass guide tube units 28a and go out of the vessel 22 through an exit 24 and irradiates a body to be examined. After the end of detection, the body to be examined is replaced with another. Since this body to be examined is different in neutron transmittivity, the speed and the wavelength of irradiating cold neutrons must be changed to photograph the body to be examined. Then, a controller 34 is commanded to synchronously rotate a pair of motors 32. Ball screws 30 are rotated at the same speed with the same rotational frequency, and a holding plate 26 falls. When the center axis of guide tube units 28b in the middle stage with the line connecting an entrance 23 and an exit 24 of a vessel 22, motors 32 are stopped. Thus, guide tube units 28a in the lowest stage and guide tube units 28b in the middle stage are exchanged.
